(Cl. 281-21) The invention relates primarily to books 01' In the drawings l is a sheet of paper bearing the type represented by magazines or pamphlets printed matter indicated by 2 on both sides therein which a plurality of signatures are associ-- of in such interrelation that when the signature ated with a paper cover. The object of the inis completed the proper pages will appear inthe s vention' is to produce a reliably united book of ri ht seq ence.

These slits are insignatures near the rear folds, the signatures d ed by 5 a d t er a e fi e Of em shown in being then attached to the cover sheet. Still F g. a t Obviously t ber may be so another customary method is th ne wh r i th more or less.

The book of the new type is compact described. y are a ed 0r co lated as 35 at the back since there are no staples to increase shOWIl in 8 and g is pp e ver the the aggregate thickness at the back. The new back edges of the assembled signatures 8 and book can be opened at all points so as to lie to these glued edges the cover section 6 is applied more or less flat, which is not possible with most as indicated in Fig. 9. The adhesive is usually 0 of the prior art publications. There are numerapplied by drawing the assembled signatures over 40 0115 Obvious advantages in the new st ucturea longitudinally grooved glue-transfer roller of h invention is illustrated in the pauywell-known type. The manipulation of the coling drawings in which Figs. 1 to 5 are successive late'd signatures during these operations induces 5 views of a sheet of printed paper in process of the open mouths t, 5 to draw glue into the inner being c nverted into a signature. Fig. 6 is a portions of the mouths so that glue has an oprear edge view of one of the signatures and Fig. 7 portunity of reaching all of the pages, though it a face view of. such a signature.

In some cases a strip of porous or open mesh fabric may be interposed between the outside of the assembled signatures and the inside of the rear cover. This is a well known procedure for which no claim is made in this case, although it could be employed in connection with the invention.

The slits or perforations may have other conflgurations than those illustrated in the drawings but the use of the slit shape has been found to be most satisfactory. It seems to allow the entry into the back of each signature of Just enough and not too much of the adhesive. Numerous changes may obviously be made with respect to a number of the details of the described procedure and it is the intent to include such variations in the appended claims.

I claim:

1. A book including at least one signature with undiminished paper areas at the hinge region of the pages, said signature being provided at the central fold thereof. with a plurality of aligned gaping open slits of substantial longitudinal extent unfilled save by adhesive material and passing through all of the pages constituting the signature, said slits alternating longitudinally with unslit portions of substantial longitudinal extent, the paper at the edges of said slits extending slightly outwardly from the fold line, a cover, and adhesive material exten i into the open slits and eflecting adhesive union as between all of the pages of the signature and as between the signature as a whole and the cover.

2. A book including at least one signature with undiminished paper areas at the hinge regionof the pages, said signature being provided at the central fold thereof with a plurality of aligned gaping open slits of. substantial longitudinal extent unfilled save by adhesive material and passing through all of the pages constituting the sig-.

nature, said slits alternating longitudinally with unslit portions of substantial longitudinal extent,

the paper at the edges of said slits extending slightly outwardly from the fold line, a cover, and adhesive material over the entire rear surface of the signature or signatures and at the projecting edges of the several pages where slitted extending into the open slits and effecting adhesive union as between all of the pages of the signature or signatures and as between the signature as a whole and the cover.
